' 2 Claims. (cr es-33) .1 V This invention relates to an attachment designed for use in connection with type casting machines, the invention embodying specifically, means for rapidly sending lines of assembled matrices, into machines for casting, without the necessity of the operator removing his .hands from the immediate vicinity of the keyboard, to accomplish the line sending in result, thereby appreciablyincreasing the speed of operation and decreasing, the amount of effort on the part of the' 'operator. 1 I l An important object of the invention is to provide an attachment of this character which may bereadilyand easily mounted on the usual type casting machine, eliminating the necessity of making extensive alterations inv the construction-of- ,the machine to mount the device. With the foregoing and other objects in view which ,will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Figure 1 is a perspective view illustrating the key board of a type casting machine; illustrating the device forming the-subject matter of the present; i nvention, as attached thereto. a I H Were-.tiaaxew .eleyetioea V the achm nt 1-]. j Fig e 3. m,aevei eeal Yi y i sectlen. .illu i ai iie. the clutch ctu -[Eg henism, taken on line 3 6f Figure 2.

Figure 4 is a sectional view through the clutch mechanism.

Figure 5 is a perspective view of the means for holding and releasing the clutch arm of the device.

Figure 6 is a sectional view taken on line 6-6 of Figure 4.

Figure '7 is a fragmental sectional view similar to Figure 6, illustrating the clutch bar as contacting with the roller of the movable section of the clutch.

Figure 8 is a fragmental sectional view through the clutch member, illustrating the clutch bar as rotating with the clutch members.

Referring to the drawings in detail, the device comprises the bracket 5 which is secured to the frame of the type casting machine with which the device is used, which bracket provides a support for the main shaft 6 of the device. One end of the main shaft 8 is provided with the-arm 1 thatmoves therewith, which arm is connected to the finger key 8 that is disposed adjacentto one side of the key board, by means of the link or rod 9.

At the opposite end of the main shaft 6, isla link It] to which the arm I l is pivotally connected, the upper end of the arm I I having pivotal connection with the arm 12 which is pivotally supported, intermediate its ends, on the plate l3 forming a part of the attachment. 1 v

This plate I3 is formedwith an opening]; through which the offset portion l6 of the arm l2 extends, the offset portion l6 providing a 0on nection between the arm l2 and the stop pin l1 The plate l3 forms a part of the main portion of the attachment, and to which the arm l8 connected, the arm extending upwardly H from the bottom 19 of the attachment or frame, where it connects with the horizontal arm 20 towhich the vertical arm 21 is connected, the arm 2| being in turn connectedhy the bolts 22 to the type casting frame.

As shown by Figure 4 of the drawings, a power shaft 23 is mounted in bearings formed in the plate [3 and plate 24 that extends upwardly from the bottom IS, the plates [3 and 24 being spaced apart. On one end of the power shaft 23, is {a pulley 25 over which the power belt26 operates, the power belt receiving its motion from a suitable power device not shown. In operation, this pulley 25 is continually rotating.

; On, the opposite end of the shaft: 23, is, a clutch which comprisesthe inner clutch member ,21, which is formed with arcuate shaped groove 28, the hub of the inner clutch member 21 being provided with an enlargement 29 that extends across the groove 28, as clearly shown by Figure '7 of the drawings.

Mounted within the groove, adjacent to the enlargement 29, is the clutch member 30 which is in the form of a roller, pivotally mounted between the walls of the groove 28, by means of the links 3|. A coiled spring indicated at 32 and which is of the expansion type, is mounted in a bore formed in the enlargement 29, one end of the spring engaging the links 3| to normally urge the clutch member outwardly or away from the enlargement 29. i

The inner clutch member is keyed to the shaft 23, so that as the shaft rotates, the clutch member will move therewith.

The clutch also includes a housing 33 which is in the form of a thick disc-like member hollowed out through a portion of its thickness, in which arm carries the horizontal stub shaft 35 on which Extending laterally from the roller 36 rotates.

the outer surface of the plate I3, is a cam'block' l 31, the cam block being formed with an opening through which the stop pin l1 extends; the stop" pin being of a length to engage the roller 36 when. i-

the roller moves over the upper surface 38 and cam block.

Thus, it will beseen that due to this construction, when-the inner clutch member-is lockedto the clutch housing 33' by means of }the arm-34 engaging the-clutch membenw'as shown by- Figure '7, the entire clutch including the inner clutch member and housing will rotate with the result that -the'roller 36 will move to a-positionover the inclined surface 33 of the-cam block'31,-and pass downwardly over the-inclined surface 39' whereit will contact with the stop pinl1 and bei held in this position, as shown by Figure- 3." It will; of course, be obvious that as thelarm 34 moves from its position within the grooveof the inner clutch member, the inner clutch member will be released and will-continue to rotate in-' dependently Iofthe housing which remains "stat n l 1' 3 I V I s The housing 33' now remains free of the inner clutch member until-the stop pin 11 is depressed and moved away from the-roller-36, whereupon the roll'er will'move downwardly, causing the arm 34 to move downwardly underthe'a'ction of: the coiled spring 43 which holds the arm 34 in posi-' tionori the housing. When the arm34 moves again-into the groove of the-inner clutch memher, the inner clutch member -upon rotation strike; the arm connecting {the inner clutch mem-' ber to the housing; l '7 j 'Exte n dingfrom-the housing 33 is a pin 41 to whichthe link 42 is connected; the link 'llz being connected to-the arm 43; through the yieldable connection 44 and turnbuckle 4 5,- theturnbucklei providing means whereby an adjustment may be made between the clutch and arm 43;. -This' "arm 43 connectswith thelever 46,-w'hich is the usual '4 actuating lever designed for actuating the mechanism that was sending in lines of assembled matrices.

What is claimed is:

l. A clutch of the class described, comprising an inner clutch member including a hub, keyed to a continuously operated power shaft, said inner clutch member having an arcuate shaped groove formed in the periphery thereof, a stop at the ends of the groove, aroller pivotally mounted within the groove adapted to engage said stop, a clutch housing in which the clutch member is rotatably mounted, said housing having an opening in the periphery thereof in registry with said 15 groove of the inner clutch member, an arm operating through said opening extending into the groove: adapted to engage the roller forcing the roller against the inner surface of the clutch housing connecting the clutch housing with the inner clutch member to rotate vtherewith, and man- I all ont d a fo e cti g n em n of saidfarm and said 'roller." 1 1 2; A clutch of the clas's described, comprising an inne'r' disc-like clutch member keyed to acon-f tinuously operating power shaft, said inner ,clutch member' having a peripheral-groove, a stopat the ends of the groove, a clutch housing in which the disc-likeclutch member operates, said hous ing having'an openingin'the periphery-thereofregistering with said groove, a reciprocating arm movable into the groove, through said openingfi' a lu chm m r ou e int' l move, e a i the stop, said arm "engagingthe-clutch member as, said shaft rotates-,-*clutching" the inner clutch member to the inner surface of the clutch-hous ing, a stationary cam member mounted eX- teriorly of the clutch housing; arollermounted on said arm movable-over said carn memberidis engaging the arm and inner clutch 'mem'ber whereby said inner clutch member moves-free of the clutch-housing, and manually-controlled means for releasing said "arm for engagement with said stop.
